COMBUSTION-SUPPORTING GAS BURNER AND BY-PRODUCT GAS BURNER

PROBLEM TO BE SOLVED: To provide a combustion-supporting gas burner which enables continuous combustion in the gas burner and has small capacity, and to provide a by-product gas burner including the combustion-supporting gas burner.SOLUTION: A combustion-supporting gas burner 3 has: a burner nozzle 41 including a jet hole 44 which jets a fuel gas FG; and a flame holding member 50 which is attached to a tip 41a of the burner nozzle 41 and forms a vortex 60 which sucks in a part of the fuel gas FG jetted from the jet hole 44. The combustion-supporting gas burner 3 is adopted to achieve the above object.SELECTED DRAWING: Figure 3 【課題】ガスバーナ内部での継続燃焼が可能な小容量の助燃用ガスバーナ及び、それを備える副生ガスバーナの提供。【解決手段】燃料ガスＦＧを噴出する噴出孔４４を備えるバーナノズル４１と、バーナノズル４１の先端４１ａに取り付けられ、噴出孔４４から噴出された燃料ガスＦＧの一部を巻き込む渦６０を形成する保炎部材５０と、を有する、助燃用ガスバーナ３を採用する。【選択図】図３
